JSON to Go API

Generate Go struct types with json tags from a sample JSON document. Integers and floats are kept apart; arrays of objects are merged into one struct.

Generate Go structs with json tags from a JSON sample. Go style names like ID and URL, int64 or float64 numbers, omitempty, pointers and inline or named nested structs.

Input

Send these as a JSON object. Unknown fields are rejected.

input: A sample JSON document (object or array). (string, required)
rootName: Name of the top-level struct. (string, up to 100 characters, default "Root")
omitEmpty: Which fields get ,omitempty: none, optional (fields missing from some samples) or all. (string, one of none, optional, all, default "none")
inline: Nest object types as anonymous structs instead of separate named types. (boolean, default false)
pointers: Use pointer types (*T) for values that are null in the sample. (boolean, default false)
anyType: Spelling of the empty interface for unknown or mixed values. (string, one of any, interface{}, default "any")
